Abstract:
... Applying the optimal 2-electron oxygen reduction reaction potential in electro-Fenton (2e⁻ORR-EF) for degradation has become a common strategy because of the highest H₂O₂ generation rate in such condition. However, in 2e⁻ORR-EF system, the Fe(III) ions crystallize on the surface of cathode and form a layer of film according to SEM, XPS, XRD and Mössbauer spectrum resulting in poor reaction rate of ...
